While the Quality Teaching framework and recent syllabus reform efforts in NSW assert the importance of valuing non-dominant cultural knowledges and values in pedagogical practice, there has been little empirical examination of the ways in which non-dominant cultural perspectives are integrated in students' learning experiences and the implications for such perspectives on students' learning outcomes. The SIPA research study draws on data from classroom observations and assessment tasks to address three questions in relation to these issues. First, in what ways are non-dominant cultural knowledges legitimised in students' classroom and assessment experiences? Second, what factors influence students' engagement with non-dominant cultural knowledge? Third, to what extent are students' learning outcomes affected by the inclusion of non-dominant cultural knowledge in pedagogy? Recent debates focused on questions such as these have been informed primarily by theoretical assumptions rather than empirical findings. By examining these theoretical assumptions in light of the NSW curriculum context, this paper will outline the framework through which the SIPA research study may inform current understandings of the practices and practicalities of pedagogies that value non-dominant cultural perspectives.
